This artist's impression shows a view of the triple-star system HD 131399 from the giant planet orbiting in the system. The planet is HD 131399Ab and appears at the lower left of the picture.

Located about 320 light-years from Earth in the constellation of Centaurus, HD 131399Ab is about 16 million years old, making it also one of the youngest exoplanets discovered to date, and one of very few directly imaged planets. With a temperature of around 1,076 degrees Fahrenheit (580 degrees Celsius) and having an estimated mass of four Jupiter masses, it is also one of the coldest and least massive directly imaged exoplanets.
